The course will provide an introduction to several important aspects of the isoperimetric problem, together with some applications to general relativity.


Topics will include:


1) The isoperimetric inequality in R^2


2) The isoperimetric inequality on surfaces with variable curvature


3) The isoperimetric inequality on minimal surfaces


4) Isoperimetric surfaces and stable constant mean curvature surfaces in Riemannian manifolds


5) The isoperimetric profile of a Riemannian manifolds


6) Quasi-local mass in general relativity





1) A basic course in differential geometry of curves and surfaces (for example chapter 1-3 from do Carmo “Curves and Surfaces”.)


2) A basic course in Riemannian geometry (for example, J. M. Lee “Riemannian Geometry”)
